Make sure the device is rooted before going forward for custom ROM installation

Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.

Users make sure they have installed USB drivers on the PC, or else your phone (Google Nexus 4) smartphone will not be recognised by the computer.

Make sure your device has more than 80% battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted midway.

Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]

Step 8: Then go back to the ClockworkMod recovery, and select 'advanced' and tap 'wipe dalvik cache' [Note: This step is optional, but many recommend this procedure so that users will not face boot loops or any other errors in the middle of custom ROM installation]

Step 9: Again come back to the main recovery screen and then tap 'install zip from SD card.'

Step 10: Then tap 'choose zip from sdcard' and go to Android 5.1 Lollipop ROM .zip file in the SD card and enter the installation process. Repeat the same procedure for installing Google Apps. [Note: use 'Volume' keys to navigate and 'Power' button to select options]

Step 11: Once done with the installation process, navigate to '+++++Go Back+++++' and re-start the device by opting 'reboot system now' seen in the recovery menu.

Now, your device (LG-Google Nexus 4) will take a few minutes to complete the booting process.

Users then head to Settings >> select 'About phone' to confirm the installation of Terminus Android 5.1 Lollipop custom ROM.
